Description

Technical Field

[0001] The present invention belongs to the technical field of photoelectric sensors, and in particular relates to an intelligent calibration auxiliary device for photoelectric sensors. Background Art

[0002] In the fields of industrial automation and precision measurement, photoelectric sensors are an important detection tool, widely used in various applications such as position detection, speed measurement, and object recognition. Photoelectric sensors operate based on the photoelectric effect, sensing changes in physical quantities in the external environment by measuring variations in light signals. However, due to process variations during manufacturing, changes in environmental factors, and wear and tear during use, photoelectric sensors require calibration before use to ensure the accuracy and reliability of their measurement results.

[0003] Traditional photoelectric sensor calibration methods typically use a pre-set moving object as the measured object. The distance between the object and the photoelectric sensor is adjusted, and the corresponding photoelectric sensor detection voltage is recorded. This method requires operators to calibrate each photoelectric sensor individually, which is not only cumbersome and inefficient, but also difficult to ensure calibration accuracy. Furthermore, differences in operator skill levels and operating habits can lead to inconsistent and uncertain calibration results.

[0004] To address these challenges, developing an intelligent calibration aid for photoelectric sensors is crucial. This device can simultaneously calibrate multiple photoelectric sensors, simplifying the calibration process and improving both efficiency and accuracy. Furthermore, by automatically recording and analyzing calibration data, the intelligent calibration aid provides operators with real-time feedback and calibration recommendations, further reducing operational complexity and improving calibration reliability and consistency. Therefore, developing an intelligent, automated calibration aid for photoelectric sensors has significant practical significance and promising applications.
